From Waste to Traffic Fuel project develops the production and use of biogas, a sustainable fuel that can be produced locally. The ultimate aim of the project is to reduce traffic-borne emissions. The two case areas (Harju and Lääne-Viru) are included that cover in northern Estonia about 45% of the Estonian population. The four case areas in Finland cover over 30 % of the Finnish population. The project is promoting biogas production and its use as transport fuel in these six case areas. Furthermore, the project will promote biowaste prevention as a first step of the regional waste policy. The project will be implemented in close co-operation with the municipal waste and sewage companies as well as stakeholders in agricultural and traffic sectors.
